Ebay isnt coming up with the goods at the moment so I've been looking into getting bent rims on car wheels refurbed.
There seem to be two schools of thought from wheel refurb companies. No dont do it from those who sell wheels and dont seem to have the kit to true rims to do it and yes do from companies that have the kit. Although they do say work is subject to assesment.
(yes this should have been in chat not bike)
